TaqI polymorphism of VDR gene in colorectal cancer and Crohn’s disease patients
Bibliographic record
Abstract
To study the relation of TaqI polymorphism of VDR gene with age, sex and the disease phenotype in patients with colorectal cancer (CRC) and Crohn’s disease (CD) from western regions of Ukraine. Fifty six patients with CRC, 46 patients with CD and 65 control individuals were included in this research. Assessment of TaqI polymorphism was performed using PCR-RFLP method. The genotype-phenotype association for this polymorphism was analyzed. The frequency of tt genotype in patients with CRC is 0.107 and among the control group is 0.138, OR (95% CI 0.248-2.246). The ratio of genotypes TT:Tt:tt in patients with CRC and in control was 37.5%:51.8%:10.7% and 44.6%:41.6%:13.8%. In men with Tt genotype the average age of CRC onset was 57.6 ± 3.6 years, in women with TT genotypethe mean age of the disease onset was 54.5 ± 4.5 years. The frequency of tt genotype in the patients with CD is 0.217 and among the control group is 0.138, OR (95% CI 0.640–4.666). The Tt genotype was detected in a half of patients with CD and TT genotype was found more frequently in control.The ratio of genotypes in men and women with CD was 38.0%:38.0%:24.0% and 20.0%:60.0%:20.0%. Among patients with CD, who underwent surgery, 33.3% individuals were carriers of tt genotype. It was confirmed no statistically significant difference in the allele frequencies and genotype distributions of Taq1 mutation in patients with CRC and CD in comparison to control group. The ratio of men and women with Tt genotype by groups of B1-B3 forms of CD behaviour according to the Montreal classification is differs, in particular, women with Tt genotype are four times more likely to have the B1 form. A study of Taq1 mutation might contribute to the identification of the groups that are at the greatest risk of severe form of CD.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
